Description
General part information
ST2L05 Series
ST2L05R3300PS is a very low quiescent current dual voltage regulator. It is specifically designed for data storage applications, this device integrates two voltage regulators, each capable of supplying 1A of current. The outputs are current-limited and overtemperature-protected. Also noteworthy is the very good thermal performance of the DFN package, with only 2°C/W of thermal resistance junction-to-case. Typical applications are hard disk drives, CD/DVD-ROMs, CD/DVD-R/RWs, COMBO® (DVD-ROM+CD-R/RW).
